around said central orifice for a purpose which preferably by a hard-drying cement or glue ap- 55 plied to its outer surface and/ or to the inside of the barrel.

In the assembly of the parts, the head is simply placed on the barrel end with the bushing therethrough extended into the recess in the barrel, and the glue-coated plug is then applied to the described fastening position through the bushing under force compressing the parts firmly together. This relation of the parts in the assemblage is illustrated in Fig. 2. The head is joined securely to the barrel as a result of the squeezing action thereon with the flange of the bushing holding it tight against the end, and with the bushing itself engaging both in the head and in the barrel. The head, bushing and plug are thus positively locked together. There can, therefore, be no separation of the parts unless the spool is broken by excessive blows or stresses. The prongs on the inner flange of the bushing engaging in the barrel body prevent any turning on the barrel, while the ribs on the bushing prevent any turning of the head, aided by the milling on the underside of said flange.

This correlation of the parts provides an extremely simple and very strong construction which is quite inexpensive to make. In actual practice it has been shown that it is the strongest and probably the least expensive construction of any now found on the market. The spool has the added advantage of true running quality on a spindle. It is therefore most useful, and permits of economies in the manufacture of textiles, whether it is used as a mill spool or as a yarn shipping spool.

It will be understood that various modifications or changes in the form or arrangement of the parts may be made within the scope of this invention. For example the heads might be of some other material than hard vulcanized fibre, such as a light, fairly soft metal, or the bores of the barrel and the inner shoulder might be polygonal instead of annular and the other parts shaped conformatively thereto. The invention accordingly is not intended to be limited by the appended claims to the specific form or construction illustrated.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is:

1. In a spool or bobbin including a barrel, a bushing member securing the head to the barrel comprising a metal ring fitting into the end of the barrel Within the head and having a flange at one end overengaging the head and another flange at the other end bearing against a shoulder in the barrel, together with prongs on the latter flange engaging in the body wall of the barrel.

2. In a spool or bobbin, a barrel, a head on the end of the barrel, a bushing fitted through the head into the barrel, and a plug fitted into the barrel through the bushing; said bushing comprising a metal ring having a flange at one end engaging over a part of the head and another flange at the opposite end bearing against a shoulder formed in the barrel, together with tooth-like projections from an edge of the last named flange engaging in the body wall of the barrel, and Wedge-like projections at the sides between the two flanges engaging in the material of the head.

3. A spool or bobbin, comprising a barrel, a head on the end of the barrel, a bushing fitted within the head and a part of the barrel, and a fastening plug fitted into the barrel through and partly within the bushing; said bushing constituting a ring of material harder than the other parts of the spool and having a flange at one end engaging over a part of the head, a flange at the opposite end engaging under the plug against a shoulder in the barrel, prong projections from the last-named flange engaging in the body of the barrel around the plug, and rib projections at the sides engaging in the material of the head.

4. A spool or bobbin, comprising a barrel, heads on the ends of the barrel, bushings fitting through the heads into the barrel with portions overengaging the former and other portions abutting wall parts of the latter; said bushings having prong projections from the abutting portions extending in the direction of the barrel axis and engaging in the wall of the barrel and rib projections at the sides extending in the same direction and engaging in the heads; and plugs secured in the barrel ends with portions thereof fitting into the bushings so as to hold the same engaging the parts as described with the heads tight against said ends.

5. In a spool or bobbin, a barrel having a recessed end with an abutment shoulder therein, a head having a central orifice registering with the recess of said end, a bushing fitting in said orifice of the head and said recess of the barrel and having a flange at one end overengaging the head around the orifice and a flange at the other end bearing against said shoulder in the barrel, a plurality of prong projections from the last named flange engaging into the body of the barrel beyond the aforesaid shoulder, a similar plurality of rib projections at the sides of the bushing engaging in the orificial edge of the head, and a plug secured in the end with the outer portion thereof fitting into said bushing and pressing upon the second named flange thereof to hold it against said shoulder.
